I know concat, but it did not work here. For the \with-url command I
need to replace the #"http" which is somehow different from the "text":
\with-url #"http" "text"
For the text part, \concat would work but for the http part I tried all
combinations of # and $ but I always got scheme errors.

How can I use scheme functions within lilypond code inside #{ #}?

I tried this:

#(define-markup-command (myfunction layout props link text)
(markup? markup?)
  "Comment."
  (interpret-markup layout props
    #{\markup \with-url #(string-append #"http" #link) #text #}))
